Paramecia is a microscopic living organism that eats bread.it also lives in water.They move evereywhere in all directions. We had difficulties trying to absurve the paramecia because they move quick.they look like little clear bubbles that are shaped like little squggles.also they can reproduce by eating food they just get cut in half lath wise and then there are 2 of them and the multiply like crazy andnthen you'll have a hole cup of microscopic paramecia.
